## S3 method for class 'listof': plot(x, ..., main, arrange=TRUE, nrows=NULL, ncols=NULL, main.panel=NULL, mar.panel=c(2,1,1,2))
x |
An object of the class "listof" .
Essentially a list of objects.
|
... |
Arguments passed to plot when generating each
plot panel.
|
main |
Overall heading for the plot. |
arrange |
Logical flag indicating whether to plot the objects
side-by-side on a single page (arrange=TRUE )
or plot them individually in a succession of frames
(arrange=FALSE ).
|
nrows,ncols |
Optional. The number of rows/columns in the plot layout
(assuming arrange=TRUE ).
You can specify either or both of these numbers.
|
main.panel |
Optional. A character string, or a vector of character strings, giving the headings for each of the objects. |
mar.panel |
Value of the graphics parameter mar controlling the size

This is the plot
method for the class "listof"
.
An object of class "listof"
(defined in the base R package) represents
a list of objects, all belonging to a common class.
The base R package defines a method for printing these objects,
print.listof
, but does not define a method for plot
.
So here we have provided a method for plot
.
In the spatstat package, the function
density.splitppp
produces an object of
class "listof"
, essentially a list of pixel images.
These images can be plotted in a nice arrangement
using plot.listof
. See the Example.
